| <dt><em>Description</em>:</dt> |
| <dd><p>This function returns the number of images in the current team, if |
| <var>distance</var> is 0 or the number of images in the parent team at the specified |
| distance. If failed is -1, the function returns the number of all images at |
| the specified distance; if it is 0, the function returns the number of |
| nonfailed images, and if it is 1, it returns the number of failed images. |
